Moreover, the first set-top box device 116can communicate with a first remote control 120, and the second set-topbox device 124 can communicate with a second remote control 128. In anexemplary, non-limiting embodiment, each set-top box device 116 and 124can receive data or video from the client-facing tier 102 via theprivate access network 166 and render or display the data or video atthe display device 118 or 126 to which it is coupled. The set-top boxdevices 116 and 124 thus may include tuners that receive and decodetelevision programming information for transmission to the displaydevices 118 and 126. Further, the set-top box devices 116 and 124 caninclude a set-top box processor 170 and a set-top box memory device 172that is accessible to the set-top box processor. In a particularembodiment, the set-top box devices 116 and 124 can also communicatecommands received from the remote controls 120 and 128 back to theclient-facing tier 102 via the private access network 166.

In an illustrative embodiment, the client-facing tier 102 can include aclient-facing tier (CFT) switch 130 that manages communication betweenthe client-facing tier 102 and the private access network 166 andbetween the client-facing tier 102 and the private network 110. Asshown, the CFT switch 130 is coupled to one or more data servers 132that store data transmitted in response to user requests, such asvideo-on-demand material. The CFT switch 130 can also be coupled to aterminal server 134 that provides terminal devices, such as a gameapplication server and other devices with a common connection point tothe private network 110. In a particular embodiment, the CFT switch 130can also be coupled to a video-on-demand (VoD) server 136.

The application tier 104 can communicate with both the private network110 and the public network 112. In this embodiment, the application tier104 can include a first application tier (APP) switch 138 and a secondAPP switch 140. In a particular embodiment, the first APP switch 138 canbe coupled to the second APP switch 140. The first APP switch 138 can becoupled to an application server 142 and to an OSS/BSS gateway 144. Theapplication server 142 provides applications to the set-top box devices116 and 124 via the private access network 166, so the set-top boxdevices 116 and 124 can provide functions such as display, messaging,processing of IPTV data and VoD material. In a particular embodiment,the OSS/BSS gateway 144 includes operation systems and support (OSS)data, as well as billing systems and support (BSS) data.

The second APP switch 140 can be coupled to a domain controller 146 thatprovides web access, for example, to users via the public network 112.The second APP switch 140 can be coupled to a subscriber and systemstore 148 that includes account information, such as account informationthat is associated with users who access the system 100 via the privatenetwork 110 or the public network 112. In a particular embodiment, theapplication tier 104 can also include a client gateway 150 thatcommunicates data directly to the client-facing tier 102. In thisembodiment, the client gateway 150 can be coupled directly to the CFTswitch 130. The client gateway 150 can provide user access to theprivate network 110 and the tiers coupled thereto.

In a particular embodiment, the set-top box devices 116 and 124 canaccess the system via the private access network 166 using informationreceived from the client gateway 150. The private access network 166provides security for the private network 110. User devices can accessthe client gateway 150 via the private access network 166, and theclient gateway 150 can allow such devices to access the private network110 once the devices are authenticated or verified. Similarly, theclient gateway 150 can prevent unauthorized devices, such as hackercomputers or stolen set-top box devices, from accessing the privatenetwork 110 by denying access to these devices beyond the private accessnetwork 166.

For example, when the first set-top box device 116 accesses the system100 via the private access network 166, the client gateway 150 canverify subscriber information by communicating with the subscriber andsystem store 148 via the private network 110, the first APP switch 138and the second APP switch 140. Further, the client gateway 150 canverify billing information and status by communicating with the OSS/BSSgateway 144 via the private network 110 and the first APP switch 138.The OSS/BSS gateway 144 can transmit a query across the first APP switch138, to the second APP switch 140, and the second APP switch 140 cancommunicate the query across the public network 112 to the OSS/BSSserver 164. After the client gateway 150 confirms subscriber and/orbilling information, the client gateway 150 can allow the first set-topbox device 116 access to IPTV content and VoD content. If the clientgateway 150 cannot verify subscriber information for the first set-topbox device 116, such as because it is connected to a different twistedpair, the client gateway 150 can deny transmissions to and from thefirst set-top box device 116 beyond the private access network 166.

The acquisition tier 106 includes an acquisition tier (AQT) switch 152that communicates with the private network 110. The AQT switch 152 canalso communicate with the operations and management tier 108 via thepublic network 112.

In a particular embodiment, the OMTswitch 160 can communicate with the AQT switch 152 via the publicnetwork 112.

In a particular embodiment during operation of the IPTV system, the liveacquisition server 154 can acquire television content from the broadcastservice 156. The live acquisition server 154 in turn can transmit thetelevision content to the AQT switch 152 and the AQT switch can transmitthe television content to the CFT switch 130 via the private network110. Further, the television content can be encoded at the D-servers132, and the CFT switch 130 can communicate the television content tothe modems 114 and 122 via the private access network 166. The set-topbox devices 116 and 124 can receive the television content from themodems 114 and 122, decode the television content, and transmit thecontent to the display devices 118 and 126 according to commands fromthe remote control devices 120 and 128.

Additionally, at the acquisition tier 106, the VoD importer server 158can receive content from one or more VoD sources outside the IPTV system100, such as movie studios and programmers of non-live content. The VoDimporter server 158 can transmit the VoD content to the AQT switch 152,and the AQT switch 152 in turn can communicate the material to the CFTswitch 130 via the private network 110. The VoD content can be stored atone or more servers, such as the VoD server 136.

When a user issues a request for VoD content to the set-top box device116 or 124, the request can be transmitted over the private accessnetwork 166 to the VoD server 136 via the CFT switch 130. Upon receivingsuch a request, the VoD server 136 can retrieve requested VoD contentand transmit the content to the first set-top box device 116 or to thesecond set-top box device 124 across the private access network 166 viathe CFT switch 130. In an illustrative embodiment, the live acquisitionserver 154 can transmit the television content to the AQT switch 152,and the AQT switch 152 in turn can transmit the television content tothe OMT switch 160 via the public network 112. In this embodiment, theOMT switch 160 can transmit the television content to the TV2 server 162for display to users accessing the user interface at the TV2 server. Forexample, a user can access the TV2 server 162 using a personal computer(PC) 168 coupled to the public network 112.

The domain controller 146 communicates with the public network 112 viathe second APP switch 140. Additionally, the domain controller 146 cancommunicate via the public network 112 with the PC 168. For example, thedomain controller 146 can display a web portal via the public network112 and allow users to access the web portal using the PC 168. Further,in an illustrative embodiment, the domain controller 146 can communicatewith at least one wireless network access point 178 over a data network176.

FIG. 3 shows a block diagram of a number of components in the remotecontrol device 128 including a two-way audio transceiver 380, aprocessor 382, a digital audio storage 384, and a LED display 386. Themicrophone 266 is coupled to the digital audio storage 384 through theprocessor 382. The LED annulus 268 is coupled to the talk button 270 andthe two-way audio transceiver 380. The talk button 270 is coupled to thetwo-way audio transceiver 380 and the digital audio storage 384. Theoptical distance measurer 272 is coupled to the two-way audiotransceiver 380. The speaker 274 is coupled to the two-way audiotransceiver 380. The audio output 276 is coupled to the two-way audiotransceiver 380. The IR transmitter 278 is in communication with theprocessor 382. The two-way audio transceiver 380 is in communicationwith the processor 382. The digital audio storage 384 is incommunication with the processor 382. The LED display 386 is incommunication with the processor 382.

The microphone 266 can be used to receive an audio input from the userof the remote control device 128. Upon the talk button 270 beingpressed, the remote control device can transmit the audio input to thesecond set-top box device 124. The LED annulus 268 can light-up,indicating that the talk button 270 has been pressed and the remotecontrol device 128 is transmitting the audio input to the second set-topbox device 124. The optical distance measurer 272 can determine adistance that the user is from the remote control device 128, such as bytransmitting a reflective optical beam from the remote control device.The speaker 274 can output a digital audio signal received by the remotecontrol device 128 from the second set-top box device 124. The audiooutput 276 can output, to an external audio device (not shown), thedigital audio signal received by the remote control device 128 from thesecond set-top box device 124. The IR transmitter 278 can transmit IRcontrol signals to the auxiliary devices. The IR control signals can beused to perform various functions on any of the auxiliary devices, suchas changing the channel, changing the volume level, and the like on thesecond set-top box 124.

Whenever any button is pressed on the remote control device 128, such aschannel up/down buttons 256 of FIG. 2, the digital audio storage 384activates and records an audio input received at the microphone 266. Theaudio input is stored in a local audio circular buffer of the digitalaudio storage 384 for a predetermined amount of time. The predeterminedamount of time can be any length of time, for example five seconds.Additionally, upon a button being pressed on the remote control device128, the two-way audio transceiver 380 activates such that the audioinput can be transmitted to the second set-top box device 124. Thetwo-way audio transceiver 380 can alternatively be placed in a sleepmode to conserve battery life if no button is pressed for apredetermined period, such as fifteen seconds. Upon the talk button 270being pressed, the remote control device 128 can execute a number offunctions at substantially the same time. The remote control device 128can set the recording mode to “start,” light-up the LED annulus 268,activate the audio digital storage 384, activate the two-way audiotransceiver 380, and trigger the optical distance measurer 272 todetermine a distance between the remote control device 128 and theuser's face.

When the recording mode is set to “start,” the remote control device 128can send the last audio input stored in the local audio circular bufferof the digital audio storage 384 to the second set-top box device 124.At substantially the same time, the remote control device 128 can send acontrol parameter embedded in a radio frequency (RF) control signal tothe second set-top box device 124. The control parameter can contain thedistance measurement determined by the optical distance measurer 272,such as four and one-half inches. Based on the control parameterassociated with the distance measurement received from the remotecontrol device 128, the second set-top box device 124 can automaticallyadjust level of audio amplification for the audio input received. Theadjustment level of the audio amplification can compensate for avariability that the user's mouth is too far away from the microphone266 or too close to it. Finally, the remote control device can changethe recording mode to “on.”

When the recording mode is “on,” the microphone 266 can continue toreceive the audio input and the two-way audio transceiver 380 can sendit as a digital audio stream to the second set-top box device 124. Uponreceiving the digital audio stream, the second set-top box device 124can stream the digitized audio packets to the multimedia applicationserver 142 over the private network 110 of FIG. 1. The multimediaapplication server 142 can process the speech input and/or pass it inreal time to a voice search engine, where the audio input can be used toperform a voice search for a specific television program. Upon receivingthe end of the audio input, the multimedia application server 142 cansend a control message to the second set-top box device 124 indicatingthe end of a speech input session.

Upon receiving the end of speech input from multimedia applicationserver 142, the second set-top box device 124 can present a visual iconon the display device 126 of FIG. 1, such as displaying a mutedmicrophone icon, indicating that the end of the speech input is reached.At substantially the same time, the second set-top box device 124 cansend an RF control signal to the remote control device 128 indicatingthe end of the speech input. Upon receiving the RF control signal fromthe second set-top box device 124, the remote control device 128 canchange the recording mode from “on” to “off.” Additionally, the remotecontrol device 128 can set the recording mode to “off” if apredetermined amount of time, such as two seconds, elapses after talkbutton 270 has been released and the audio input level is below apredetermined level. When the recording mode is changed from “on” to“off,” the remote control device 128 can turn off the LED annulus 268,and set the microphone 266 and two-way audio transceiver 380 to sleepmodes to conserve the battery.

The multimedia application server 142 can also send a control message tothe second set-top box device 124, requesting that the set-top boxdevice send a variety of RF-based control signals to the remote controldevice 128. For example, one control signal can cause the remote controldevice 128 to play a short audio file stored on the digital audiostorage 384 through the speaker 274. This feature can enable the user tolocate the remote control device 128 if it is missing. Another controlsignal can cause the remote control device 128 to turn off the LEDannulus 268 and to end transmission of the audio input. The multimediaapplication server 142 can also send a “play list” to the remote controldevice 128 via the second set-top box device 124. The play list cancontain a set of channel numbers, which can be stored on the remotecontrol device 128. This feature can be used to select a number of“favorite” broadcast channels by scrolling the list stored on the remotecontrol device 128 via the LED display 386.

Also, the second set-top box device 124 can automatically scan the RFband over which the remote control device 128 is operating, such as twoand two-fifths GHz. If there is any RF interference from other RFdevices in a surrounding area, the second set-top box device 124 canautomatically choose an RF channel with less interference and then senda control signal to the remote control device 128. The control signalcan request that the remote control device re-synchronize the signalband with the set-top box device 124.

The remote control device 128 can be used to transmit a voice command tothe second set-top box device 124. FIG. 4 shows a flow diagram of amethod 400 for outputting a voice command to the set-top box device. Atblock 402, an audio input is received at a remote control device. Theaudio input is stored in a digital audio storage device at block 404. Atblock 406, determination is made whether a talk button is pressed andheld. If the talk button is not pressed, then a determination is madewhether a specific amount of time passes at block 408. The specificamount of time is measured from the first audio input received. At block410, if the specific amount of time lapses, then the audio input storedin the digital audio storage device is erased. An additional audio inputis received at block 412 and the flow diagram continues at block 404. Ifthe specific amount of time has not passed, then an additional audioinput is received at block 412 and the flow diagram continues at block404.

If the talk button is pressed, then an LED annulus is turned on at block414. At block 416, the audio input is recorded. A determination is madewhether the talk button is released at block 420. If the talk button isnot released, an additional audio input is received at block 418 and theflow diagram continues at block 416. At block 422, if the talk button isreleased, the LED annulus is turned off. Additional audio input isreceived at block 424. At block 426, a determination is made whether avolume of the speech received at the microphone is below a specificlevel. If the volume of speech is not below the specific level, then theaudio input is continually received at block 424. If the volume ofspeech is below the specific level, then the audio input is outputted asa voice command at block 428. The voice command can be outputted to aset-top box device to perform a function associated with the voicecommand.

The remote control device 128 can also be used to transmit a controlparameter, for varying an amplification of a voice command signal, tothe set-top box. FIG. 5 shows a flow diagram of a method 500 for varyingthe amplification of the voice command signal from the remote controldevice. At block 502, an indication that a talk button has been pressedis received. An audio input is received at block 504. At block 506, anoptical beam is transmitted. A reflection of the optical beam isreceived at block 508. At block 510, a distance to a user is determinedbased on the reflection of the optical beam received. A determination ismade whether the distance to the user is less than a first specificamount at block 512. If the distance is less than the specific amount,then a first control signal requesting a decrease in the amplificationof the voice command signal is sent to the set-top box device at block514. If the distance is not less than the first specific amount, then adetermination is made whether the distance is less than a secondspecific amount at block 516. If the distance is less than the secondspecific amount, then a second control signal requesting no change inthe amplification of the voice command signal sent to the set-top boxdevice at block 518. If the distance is not less than the secondspecific level, then a third control signal requesting an increase inthe amplification of the voice command signal is sent to the set-top boxdevice at block 520.
